Willow Warbler

Phylloscopus trochilus

ABA Rarity Code: 5

A recent addition to the avifauna of North America, this species has proved to be a semi-regular vagrant to the Pribilofs in the fall during the 2010s. Recent records have mostly been clustered during the final week of August, which is likely the best time to look for this species in the islands, though an outlier record from late September suggests that occurrences could happen through much of the fall period.
